Abstract

A swampland has considerable potential in agriculture. This land has high soil acidity level, and high iron content. Therefore, the application of ameliorant to acid sulfate soil is essential to improve the soil and make it more suitable for rice cultivation. This study aimed to know the effects of phosphorus (P) from Moroccan Rock Phosphate (MRP) and fertilization on swamp rice (Oryza sativa L.). The experiment was conducted at the experimental location of Indonesian Swampland Agricultural Research Institute (ISARI), Puntik Village, Barito Kuala District, South Kalimantan and arranged in a randomized nested design consisting of 100 kg.ha-1 TSP (Control), 750 kg.ha-1, 1,000 kg.ha-1, and 1,250 kg.ha-1 Moroccan rock phosphate with four replications in each treatment.  The yield component of grain increased significantly at 3.77 ton.ha-1. The highest of grain yield was obtained in the application of 1,000 kg.ha-1 MRP. Meanwhile, significant positive correlation was observed between plant height and the number of spikelets per panicle. The application of phosphate fertilizer can increase soil pH, which affects the growth and yield of rice plants such as plant height and yield.

Abstract

In Indonesia, the superior sweet cassava varieties are still limited due to the situation on which the majority of the superior varieties -bitter varieties- are used as industrial raw material until now. Therefore the availability of new high yielding of sweet cassava varieties is still needed. Assembling varieties requires the support of germplasm that has identified its superiority. The research objective was to evaluate tuber yield, morphology, and physico-chemical properties of cassava tuber from sweet cassava germplasm. A total of 75 accessions were characterized in Jambegede research station in February-November 2016, using Randomized Block Design. Variables observed included plant height, number of plants at harvest, harvest index, number and weight of tuber yield, and starch content. Physico-chemical analysis of tubers was carried out on 15 accessions with high tuber yields. Plant height at harvest was 393.2 cm in average. There were 10 accessions of sweet cassava with high fresh tuber yields ranging from 36.61 ton.ha-1 to 61.64 ton.ha-1, i.e MLG 10366, MLG 10365, MLG 10318, MLG 10197, MLG 10325, MLG 10341, MLG 10018, MLG 10279, MLG 10298, and MLG 10263. Physico-chemical analysis showed that the average of HCN content was 9.40 ppm, moisture content of 59.5 %, starch content of 28.8 % wb, and amylose content of 11.0 % wb. The bitter cassava with steamed tuber texture not cracked had relatively higher levels of HCN and water content, which was 82.88 ppm and 74.8 %, while the starch and amylose content was relatively lower (15.8 % wb and 5.5 % wb).

Abstract

Two cultivars of local rice, namely Mentik Wangi and Mentik Susu, have been grown around west to south flank of Merapi volcano. They are highly valued for their good taste and cooking characteristics. An attempt to introduce drought-tolerant rice varieties has been conducted by crossing them with two sources, namely Kasalath and Bluebonnet. Molecular-assisted selection using a set of SSR markers was applied to check the F1 and F2 generation trueness and segregation. This research was conducted in the facilities of Department of Agronomy, Faculty of Agriculture, Universitas Gadjah Mada, Yogyakarta. The research was a field experiment arranged in a completely randomized design, consisting of Mentik Wangi, Mentik Susu, Bluebonnet, and Kasalath, as well as their crossings’ F1 and F2 plants as treatments. The SSR markers used are RM72, RM228, RM518, and RM20(A). Polymorphism test of the parents showed that polymorphism exists between local and donor parents, thus these markers were considered eligible for the F1 and F2 tests. The heterozygous individuals of F1 were 75% for Bluebonnet × Mentik Wangi, 44.4% for Bluebonnet × Mentik Susu, and 46.7% for Mentik Wangi × Bluebonnet; all were consistent in every primer used. We could not confirm that the F2 populations showed segregation pattern that followed Mendelian segregation in some crosses due to too small size of the sample. Heterozygous individuals in F2 showed the differences pattern for each marker, indicating that the location of the SSR markers were far from each other in the genome.
